anti estrogen streiods Tamoxifen Citrate is a Selective Estrogen Receptor Modulator (SERM) that was created in 1961 by ICI now known as AstraZenaca. There are numerous brands including generic forms of Tamoxifen Citrate on the market, but Nolvadex is the most well known. Often referred to as an anti-estrogen, Tamoxifen Citrate is actually both an antagonist and agonist. This means it will act as an anti-estrogen in certain areas of the body while acting as an estrogen in other areas.

​​anti estrogen streiodsTamoxifen Citrate has been used medically for decades and has been highly successful in breast cancer treatment, specifically hormone-responsive breast cancer. It is also a medication that is used by many anabolic steroid users, but it is not a steroid. This is a drug steroid users will sometimes use during steroid use to help with estrogenic related side effects brought on by specific steroids. However, it is most commonly used during Post Cycle Therapy (PCT). PCT is the 3-6 week period following steroid use that is implemented in order to help with natural testosterone production that is suppressed during anabolic steroid use.

Application:

Tamoxifen has been used for analyzing its effects on radiation sensitivity and steroid receptor content in human breast cancer cells[1]. It has also been used for studying the accumulation of triacylglycerol in hepatic tissues of female rats[2]. Furthermore, studies have reported that environmental magnetic fields can block antiproliferative functions of tamoxifen in human breast cancer cells.

Effects of Tamoxifen Citrate:

For the anabolic steroid user the positive effects of Tamoxifen Citrate can be seen both during and post anabolic steroid use with post use being primary.Anabolic steroids like Testosterone and Nandrolone among others will increase the body’s serum estrogen levels. This occurs by the testosterone hormone converting to testosterone, which happens due to it being metabolized by the aromatase enzyme. Once aromatized you have more estrogen, and this can lead to gynecomastia and water retention. It can also lead to high blood pressure if water retention becomes severe. Tamoxifen Citrate does not lower serum estrogen levels, but it will bind to the receptors in the chest preventing the estrogen from binding. It will not do a lot for water retention if that is an issue. It is also not enough gynecomastia protection for all men, but that depends on how high estrogen levels go as well as genetics. If more or stronger protection is needed Aromatase Inhibitors (AI’s) are recommended. AI’s are anti-estrogens that inhibit aromatase activity and lower serum estrogen levels.​​

We then have the testosterone stimulating effects of Tamoxifen Citrate. This is by far the most important effect for the anabolic steroid user. When we use anabolic steroids we suppress our natural testosterone production, and this will occur regardless of the steroids used. Steroid use creates a negative feedback and tells your pituitary to stop making LH and FSH. This is why almost all steroid cycles include exogenous testosterone so that the negative feedback doesn’t cause a low testosterone level. Once steroid use is complete something is then needed to jump start testosterone production. It will occur on its own, but it will be slow and Tamoxifen can both speed it up and make it more efficient. Tamoxifen Citrate is introduced, LH and FSH levels go up and as a result testosterone is produced.
